IGS站观测数据和相关产品下载地址，主要采用ftp方式，其中个别IGS站，可能仅在个别机构提供，例如这个ulab站，在sopac、cddis上没有提供，仅在IGN（欧洲IGS数据中心）有提供，而且提供2种形式，rinex2和rinex3文件命名方式。
RINEX 3文件命名方式为：
<SSSS><MR><CCC><S><YYYYDDDHHMM><NNN><FRQ>_<TT>.<FMT>.gz
例如：MAS100ESP_R_20142350000_01D_30S_MO.crx.gz
文件名各部分释义：
<SSSS> 为观测站点名；
<MR> 为接收机编号；
<CCC> 为三位 ISO 3166-1 标准的国家代码，标识站点位置，中国代码 CHN；
<S> 为数据源，即数据来源于接收机（R）还是数据流（S）；
<YYYYDDDHHMM> 为观测开始时刻（年、年积日、时、分）；
<NNN> 为观测时段长度，01D = 1 day，；
<FRQ> 为观测时的采样间隔或采样频率；
<TT> 为包含的卫星系统和数据类型，第一位表示卫星系统（M、G、R、C、E、J、I）；第二位为数据类型，即观测文件（O）、导航文件（N）或气象文件（M）；
<FMT> 为扩展名，扩展名只有两种：rnx 或 crx。
.gz为压缩格式
另外，这个IGN网站网速很慢，可以利用ftp下载软件，采用文件名过滤的方式，批量下载，如果采用命令方式容易长时间网络连接假死。
